class text_encoding::aliases_view : public ranges::view_interface<text_encoding::aliases_view> |  | (since C++26)

The nested class `text_encoding::aliases_view` is a `view` over aliases of the character encoding.

Let r denote an instance of `aliases_view`. For a non-empty range r:

- r.front() is the primary name of the registered character encoding,
- r contains the aliases of the registered character encoding such that the order of the aliases is unspecified,
- each element in r is a non-null and non-empty null-terminated byte string encoded in the literal character encoding and comprising only characters from the basic character set, and
- r does not contain duplicate values when compared with std::strcmp.

These are the following type properties of `text_encoding::aliases_view`:

- it models `copyable`, `random_access_range`, and `borrowed_range`.
- it is not required to satisfy `common_range` and `default_initializable`.
- both ranges::range_value_t<text_encoding​::​aliases_view> and ranges::range_reference_t<text_encoding::aliases_view> denote const char*.
- ranges::iterator_t<text_encoding::aliases_view> is a ConstexprIterator.

### Member functions

begin | returns an iterator of implementation-defined type to the beginning of the aliases view (public member function)
end | returns a sentinel of implementation-defined type of the aliases view (public member function)
##### Inherited from std::ranges::view_interface
empty | returns whether the derived view is empty. Provided if it satisfies `sized_range` or `forward_range`. (public member function of `std::ranges::view_interface<D>`)
cbegin (C++23) | returns a constant iterator to the beginning of the range. (public member function of `std::ranges::view_interface<D>`)
cend (C++23) | returns a sentinel for the constant iterator of the range. (public member function of `std::ranges::view_interface<D>`)
operator bool | returns whether the derived view is not empty. Provided if ranges::empty is applicable to it. (public member function of `std::ranges::view_interface<D>`)
front | returns the first element in the derived view. Provided if it satisfies `forward_range`. (public member function of `std::ranges::view_interface<D>`)
operator[] | returns the `n`th element in the derived view. Provided if it satisfies `random_access_range`. (public member function of `std::ranges::view_interface<D>`)

## std::text_encoding::aliases_view::begin

constexpr /*implementation-defined*/ begin() const; |  | (since C++26)

Returns an iterator of implementation-defined type to the beginning of r.

## std::text_encoding::aliases_view::end

constexpr /*implementation-defined*/ end() const; |  | (since C++26)

Returns a sentinel of implementation-defined type of r.
